245		3	_aAn assay of growth inhibitors in seed oil and normal and diseased (brown bast) bark of Hevea
520			_aThis paper was presented at the International Rubber Conference 1973 in Sri Lanka. Content of growth inhibitors was significantly higher in diseased than in healthy rubber bark but it is not yet established that the increase causes the disease. High yielding clones are generally more susceptible to brown bast and may have susceptibility bred in to them.
